FS-85 Application

  • FS-85 is niobium high temperature alloy, which is widely used in aerospace industry. It can be used as a structural material for the shuttle engines, rocket nozzles and hot exchange pipes for jet planes.

  • FS-85 is a high strength niobium alloy. With niobium as the base metal, a large amount of tungsten, molybdenum, titanium, zirconium and other metal elements and a small amount of carbon element were added into FS-85.The C129Y niobium alloys forms solution strengthening and it combines with Nb and Zr to form niobium alloys such as FS 85.This kind of alloy has high tensile strength, creep strength and fatigue strength in the range from 1300 ˚C to 1600˚C.
